The correct amperage should be marked on the back panel near (or on) the fuse holder. I don't believe the voltage is as critical as the correct amperage and the slo blow type. It's more than likely a bad rectifier or power tube if it keeps happening. Good luck.

THIS!
This has happened to me a few times. You 'think' it's a fuse issue (because it repeatedly blows)....but in actuality, the fuse is doing what it's supposed to do...protecting the amp from a bad rec or power tube.

My money would be on the rectifier.

Had the same issue with a Rt66. New rectifier fixed it right up n

Repeated fuse blowing (if the value is correct) indicates that root cause is something else. Repeat blowing can also take other components down.

DC here!
All the above is excellent advice - but I have had fuses blow for no appearnt reason - Mind you that that IS NOT common
I get the feeling that fuses sometimes simply wear out- or... maybe the quality of the fuses simply vary over long production runs - or
maybe when dealing with transistor amps without the relay delay (no pun intended ) during power on/of cycles - the power surge over time wear the fuse down....?
Just a thought - as I said that is not something happening every day - to understate it .
Start by follow the earlier advice given above & you should be fine. Besides the good Doc is always willing give advice & lend a helping hand.
Cheers: Dixiechicken!
